Outrigger Monitoring System (OMS) CCS
Display
The Outrigger Monitoring System (OMS) aids the operator
by automatically identifying the horizontal position of each
outrigger beam. The OMS uses four sensors, one per
outrigger beam, to identify when an outrigger beam is
positioned to one of four pre-defined locations, including
retracted, partial extend, mid-extend, and full extend.
Set up of the outriggers is the same for cranes equipped with
OMS; refer to Outrigger Controls and Indicators, page 3-14
or Outriggers, page 3-93. The CCS only indicates the
horizontal position of the outrigger beam and should not be
used to confirm proper crane setup.
When an outrigger is not properly deployed the outrigger
symbol will light up red and the operator will need to properly
deploy the outriggers for the rigging code selected.
NOTE: If an outrigger symbol and its associated distance
number does not display then that sensor is not
properly calibrated or has failed.
Stowing the Outriggers
1. Push the Center Front Jack control button to ACTIVATE
and retract the center front jack,
2. Press both the left rear jack button and the right rear jack
button, plus the retract button until the rear jacks have
retracted several inches.
3. Press both the left front jack button and the right front
jack button, plus the retract button until the front jacks
have retracted several inches.
4. Repeat steps 2 and 3 until the crane is resting on all
wheels and the jack floats are several inches off the
ground.
5. Release the locking levers and allow the floats to drop to
the ground.
6. Continue to retract the jacks until fully retracted.
7. Refer to “Stowing the Partial/Mid Extension Lock Pin” on
page 4-36 if the crane was operated at the partial or mid-
extend position. Push the appropriate outrigger selector
button to FRONT EXTENSION or REAR EXTENSION
and push the Extension/Retraction Switch to RETRACT
to retract each outrigger beam.
NOTE: More than one outrigger may be retracted at a time.
8. Stow the outrigger floats.
Stowing the Partial/Mid Extension Lock Pin
NOTE: If the lock pin is wedged in the hole in the outrigger
beam, it may be necessary to jog the outrigger
Extension/Retraction pushbutton slightly while
pulling on the pin.
1. Rotate handle of lock pin to align guide pin with slot in
hole while pulling on pin and return pin to stowed
position.
2. Remove locking pins from side of the outrigger beam. If
the pin will not freely disengage from the hole, slowly
extend or retract the outrigger beam to allow the locking
pin to disengage from the holes.
3. Fully retract outriggers.
4. Install the locking stirrup over the retainer lug and install
retaining pin, refer to Figure 4-28.
5. Stow locking pin in the pin stowage bracket located at
the frame.
6. Install travel locking pin in outrigger box before traveling
to prevent beam creep, refer to Figure 4-29.
WARNING
Tipping Hazard!
The crane can overturn, causing death or serious injury or
sustain serious damage from operating the crane from
outrigger positions other than the position specified on the
selected load chart.
The OMS is an operator’s aid only, measurements from
the OMS system are not used by the CCS. The operator
must select the proper rigging code.
CAUTION
Keep feet and hands clear of the floats when unlocking
them from the jacks.
